This Neolithic ovoid stone setting known as Beddarthur (Arthur’s Grave) is situated immediately beneath Carn Bica (SN 129325), roughly between Carn Sian and Carn Menyn on Mynydd Preseli.
Although full photographic horizon panoramas were taken on site during the pilot study, these will have to wait until the full Landscape & Perception project is funded and in operation to be fully analysed. But what is immediately apparent is that Beddarthur dramatically overlooks the Carn Menyn outcrops, probably the main source of the Stonehenge bluestones.
The site was briefly tested for acoustics but none of the set stones displayed any clear ringing qualities.
This small carn overlooks Beddarthur, and has fine views eastwards to Carn Menyn beyond. Because of showery conditions and time/daylight considerations, we were unable to fully explore the carn acoustically during the pilot study, but we gained the impression that there were probably a number of lithophones contained within the outcrop (was this the reason the Neolithic peoples built a monument at the foot of it?). We noted in particular one large rock on the eastern side of the carn, directly overlooking Beddarthur, and, beyond, Carn Menyn. When struck with a hammerstone, it issues tones reminiscent of a gong mixed with a tin drum. When the full Landscape & Perception project is fully funded and operational, we will conduct a thorough acoustic investigation of Carn Bica.
Carn Bica and Beddarthur are on the eastern flanks of Carn Sian, the summit of which provides fine vistas eastwards over Carn Menyn and beyond.
